Sigma-Aldrich® Recognized By Carbon Disclosure Project (CDP) for Climate Change Disclosure

ST. LOUIS, Oct. 1, 2012 /PRNewswire/ -- Sigma-Aldrich Corporation (Nasdaq: SIAL) was recently recognized by the Carbon Disclosure Project (CDP), an independent not-for-profit organization working to drive greenhouse gas emissions reduction and sustainable water use worldwide, for its innovative approach to the disclosure of climate change information.

"Sigma-Aldrich recognizes that the sustainability of our business depends on making smart choices regarding resource usage, which in turn affects the products delivered to customers and ultimately our communities," said Rakesh Sachdev, Sigma-Aldrich President and CEO. "Good global citizenship benefits the Company and all of its stakeholders and we are proud to be commended for our efforts."

This is the first year Sigma-Aldrich has been featured in CDP's "Carbon Disclosure Leadership Index." The index highlights companies within the S&P 500 Index that take a strong approach to information disclosure regarding climate change. Companies are scored on their climate change disclosure with high scores indicating proficient internal data management and understanding of climate change related issues affecting the Company.

"Sigma-Aldrich has set a number of goals designed to reduce the intensity of natural resource use by 2015," said Jeffrey Whitford, Global Citizenship Manager. "We are also planning an in-depth evaluation of our supply chain to determine additional ways to reduce environmental impact. We have made great progress to date, but we know there is more work to be done."

The index, compiled by PwC on behalf of CDP, provides an evaluation tool for institutional investors and other stakeholders. This year it includes 53 companies from the S&P 500 based on analysis of their responses to CDP's questionnaire, which focused on greenhouse gas emissions, emissions reduction targets and the risks and opportunities associated with climate change.

"Companies that make the Carbon Disclosure Leadership Index demonstrate strong internal data management practices for the measurement of greenhouse gas emissions and energy use," said Paul Simpson, Chief Executive Officer of CDP. "They are also giving clear consideration to the business issues related to climate change and their exposure to climate-related risks and opportunities. This is vital to realizing greater efficiencies, protecting the business from risk and capitalizing on opportunities."
